Question

which of the following is not an example of the benefits of good cardio - respiratory endurance?
a. less body fat.
b. smaller arteries.
c. lower risk of heart disease.
d. a more efficient heart.
e. higher levels of energy.

Explanation:

Cardio - respiratory endurance is related to the heart, lungs, and blood vessels working together. Regular exercise for cardio - respiratory endurance helps in burning fat (so less body fat is a benefit), makes the heart more efficient (as it pumps blood better with less effort), reduces the risk of heart disease (by keeping the cardiovascular system healthy), and increases energy levels (as the body can supply oxygen more effectively to muscles). However, good cardio - respiratory endurance does not lead to smaller arteries. In fact, regular aerobic exercise can improve the elasticity and diameter of arteries in a healthy way (through processes like angiogenesis and improved endothelial function).

Answer:

B. Smaller arteries.
